3-16.4.3 MULTIPLE STATIONS

Where simultaneous use of two or more hose lines from a single bank of cylinders is possible,

a quantity of carbon dioxide shall be available to support the maximum number of hoses that

are likely to be used at any one time for at least 1 minute. All supply piping shall be sized for

the simultaneous operation of these hoses.

3-16.4.4 CARBON DIOXIDE SUPPLY

A separate carbon dioxide supply can be provided for hand hose line use, or carbon dioxide can

be piped from a central storage unit supplying several hose lines or from fixed manual or

automatic systems. Where hand hose lines are provided for use on a hazard protected by a

fixed system, separate supplies shall be provided unless sufficient carbon dioxide is provided

to ensure that the fixed protection for the largest single hazard on which the hose lines can be

used will not be jeopardized.

All controls for actuating the system shall be located in the immediate vicinity of the hose reel

or rack. Operation of hand hose line systems depends upon manual actuation and manual

manipulation of the horn and valve assembly. Therefore, speed and simplicity of operation are

essential for successful extinguishment. Refer to Paragraph 3-13 for additional information on

actuation systems.

The use of a Grooved Nut Discharge Head, P/N 81-872442-000, with a Lever Operated Control

Head, P/N WK-870652-000, allows the operator to actuate only one cylinder at a time in a

multiple cylinder bank and to close the cylinder valve without discharging the entire contents

of the cylinder.
